Stretches of flat land, also known as plains, are large areas of land that are relatively level and have few or no hills. Plains are usually covered in grasses, shrubs, and other low-lying vegetation. They are often found in regions with a dry climate, such as the Great Plains of North America. Plains can also be found in wetter climates, such as the pampas of South America. Plains are important habitats for many species of wildlife, and they are also used for agricultural purposes.
